Abstract

Arrangement for continuous mixing of mortar with a basically vertical circular supply container, with stirring paddles, a water supply and a pump, has the mixing tube, with screw, attached to the square or rectangular discharge opening, off centre in the bottom of the container. The tube sloping downwards at an angle contains the mixing pump, mixing shaft, and final discharge worm shaft. The discharge opening is closed by a flat disc running on flat steel slides. This arrangement requires only comparatively small stirring paddles, and motor and is effective in fully emptying the storage container.

Description

Zusatzpatentanmeldung zur Patentanmeldung P 23 40 246.2 -Kontinuierliche Mi schpumpe Die Erfindung bezieht sich auf eine Weiterentwicklung der in Patentanmeldung P 23 40 24-6.2 beschriebenen kontinuierlichen Mischpumpe.Additional patent application to patent application P 23 40 246.2 -continuous Mi pump The invention relates to a further development of the patent application P 23 40 24-6.2 described continuous mixing pump.

Verschiedentlich werden auf Baustellen anstelle der senkrechten, kreiszylindrischen Silos, welche unten mit konischem Boden enden, auch solche Behälter verwendet, welche bei kreiszylindrischem oder leicht kegeligem Mantel einen ebenen Boden aufweisen. Hier wird das Problem des Austragens der Schüttgutmassen durch eine bestimmte, im Boden zentrisch oder exzentrisch angeordnete Öffnung in an sich bekannter Weise mit bodenbestreichenden, einfachen Rührarmen gelöst. Der Antrieb für diese Rührarme kann wahlweise ausserhalb oder innerhalb des Vorratsbehälters liegen, je nachdem, welche Anordnung zweckmäßig ist und welche Antriebsenergie zur Verfügung steht.Different are used on construction sites instead of the vertical, circular cylindrical Silos, which end with a conical bottom, also used such containers, which have a flat bottom in the case of a circular cylindrical or slightly conical jacket. Here the problem of discharging the bulk material is solved by a certain, im Bottom centrally or eccentrically arranged opening in a known manner solved with simple stirring arms that brush the ground. The drive for these agitator arms can be either outside or inside the storage container, depending on which arrangement is appropriate and which drive energy is available.

Auf diese Weise wird das häufige Problem des Austragens aus konischen Öffnungen von Silos mit dem Vorteil gelöst, daß ein größeres Volumen im Vorratsbehälter unterzubringen ist, weil ein zylindrischer Behälter mit ebenem Boden mehr fasst als ein konischer Behälter, vorausgesetzt gleiche Höhe.This way, the common problem of bleeding out becomes conical Openings of silos solved with the advantage that a larger volume in the storage container is to be accommodated because a cylindrical container with a flat bottom holds more than a conical container, provided the same height.

Diese Lösung hat sich auch als zweckmäßig erwiesen bei kleineren Vorratsbehältern, welche 5 - 10 Sack Material aufnehmen müssen bei möglichst geringer Einfüllhöhe.This solution has also proven to be useful for smaller storage containers, which have to hold 5 - 10 sacks of material with the lowest possible filling height.

In der Praxis sind auch solche Maschinen mit kleinem Vorratsbehälter und daran montierter Mischpumpe bekannt. Bei diesen ist jedoch der Materialaustritt am unteren Ende des senkrechten Mantels, d.h. oberhalb vom Boden, angeordnet. Die Pumpe ist hier also seitlich am Vorratsbehälter montiert. Diese bekannte Ausführung hat den Nachteil, daß sich bei fast leerem Vorratsbehälter das Material nur schwer in gleichmäßiger Menge austragen läßt. Dies begründet sich dadurch, daß das Material durch die Rührflügel an der verhältnismäßig schmalen Austrittsöffnung im Mantel vorbeigeschleudert wird.In practice, such machines are also used with a small storage container and mixing pump mounted thereon. In these, however, is the material outlet at the lower end of the vertical mantle, i.e. above the floor. the The pump is therefore mounted on the side of the storage tank. This well-known version has the disadvantage that it is difficult to find the material when the storage container is almost empty can be discharged in an even amount. This is due to the fact that the material through the agitator blades at the relatively narrow outlet opening in the jacket is thrown past.

Um diesen Effekt weitgehend zu kompensieren, werden großflächige Rührarme verwendet. Diese benötigen wiederum bei vollem Vorratsbehälter und schwerem Material sehr viel Drehmoment und Energie. Die dadurch stark zu dimensionierenden Motoren sind auf Baustellen sehr lästig wegen des hohen Gewichts und der großen Stromaufnahme.In order to largely compensate for this effect, large-area agitator arms are used used. These, in turn, are required when the storage container is full and the material is heavy a lot of torque and energy. The motors that have to be dimensioned as a result are very annoying on construction sites because of their high weight and high power consumption.

Bei der erfindungsgemäßen Lösung wird die schräge Mischpumpe 2 mit ihrem Zwischenrohr 6 gegen eine Flanschöffnung 13 im waagrechten Boden des Vorratsbehälters 10 befestigt. Damit der Pumpenmotor 1 gut zugänglich bleibt, wird die Entleeröffnung 13 vorzugsweise exzentrisch im kreisrunden Boden des Vorratsbehälters 10 angeordnet, möglichst mit einer Seite bündig zum Mantel des Vorratsbehälters 10.In the solution according to the invention, the inclined mixing pump 2 is with their intermediate pipe 6 against a flange opening 13 in the horizontal bottom of the storage container 10 attached. So that the pump motor 1 remains easily accessible, the drain opening 13 arranged preferably eccentrically in the circular bottom of the storage container 10, If possible with one side flush with the jacket of the storage container 10.

Die Anordnung der Füllöffnung im Boden mit den darüberstreichenden, einfachen Rührarmen 11, die aus schwachen Rundeisen ausgebildet sein können, hat den Vorzug, daß das Material ohne große Nachhilfe sehr leicht das Zwischenrohr 6 passiert und in .großer menge in die Mischpumpe 2 fällt. Dort wird das Gut von der schneckenförmig ausgebildeten Rührwelle 4 erfasst und mit Wasser vermischt zur Schneckenpumpe 3 gedrückt.The arrangement of the filling opening in the floor with the simple stirring arms 11, which are formed from weak round iron be can, has the advantage that the material can easily reach the intermediate tube without much tuition 6 happens and falls into the mixing pump 2 in a large amount. There is the good of the screw-shaped agitator shaft 4 detected and mixed with water for Screw pump 3 pressed.

Das Zwischenrohr 6 wird hierbei zweckmäßig als rechteckige Schachtöffnung ausgebildet, welche radial zur Mitte des Vorratsbehälters hin eine große Erstreckung hat. Dadurch ergibt sich ein großer Querschnitt. Die Folge ist, daß auch bei geringem Füllstand im Vorratsbehälter 10 und schwachen Rührarmen 11 mit dem Vorteil geringen Energieaufwandsund leichtem Rührmotor 16 stets gleich viel Trockenmaterial der Mischpumpe zugeführt wird bis zu dem Moment, wo der Vorratsbehälter tatsächlich leer ist.The intermediate pipe 6 is here expediently as a rectangular shaft opening formed, which radially towards the center of the storage container a large extent Has. This results in a large cross-section. The result is that even with little Level in the storage container 10 and weak agitator arms 11 with the advantage of low Energy expenditure and light stirrer motor 16 always the same amount of dry material from the mixing pump is supplied until the moment when the storage container is actually empty.

Dies ist insofern von erheblicher Bedeutung, weil dann die Mischpumpe aufgrund ihres Funktionsprinzips eine konstante Mörtelkonsistenz aufbereitet und pumpt bis unmittelbar zum Leerwerden des Vorratsbehälters.This is of considerable importance because then the mixing pump Due to its functional principle, a constant mortar consistency is prepared and pumps until the storage container is empty.

Dies hat sich gegenüber den eingangs beschriebenen, bekannten Vorrichtungen als vorteilhaft erwiesen.This has proven to be the case with the known devices described at the outset proven beneficial.

Anstelle einer Drehklappe wird bei dieser Ausgestaltung der Erfindung als Absperrorgan ein Flachschieber 7 verwendet. Da erfahrungsgemäß bei Verarbeitung von gipshaltigen Mörteln alle gleitenden Teile sehr schnell fest werden durch den quellenden Gips, wird erfindungsgemäß vorgeschlagen, den Flachschieber 7, betätigt durch den Hebel 8, im wesentlichen ohne Führungselemente auszustatten sondern ihn-lediglich auf schmalen Flacheisen-Nocken 14 gleiten zu lassen, welche mit 10 - 20 mm Breite an den seitlichen, geraden Rändern der Entleeröffnung 13 befestigt sind. So besteht keinerlei Möglichkeit, daß Gipsreste zwischen Flachschieber 7 und irgend welchen geschlossenen Führungsleisten eingeklemmt werden und der Schieber 7 stets gängig ist.Instead of a rotary flap, in this embodiment of the invention a flat slide valve 7 is used as a shut-off device. As experience shows when processing from mortars containing gypsum, all sliding parts become solid very quickly through the swelling plaster is proposed according to the invention, the flat slide 7 actuated by means of the lever 8, essentially without guiding elements, but merely equipping it to slide on narrow flat iron cams 14, which are 10-20 mm wide are attached to the lateral, straight edges of the emptying opening 13. So there is no possibility that plaster residues between flat slide 7 and any closed guide strips are clamped and the slide 7 is always running is.

Bei einem weiteren, denkbaren Ausführungsbeispiel der Maschine kann die Mischpumpe 2 mit ihrer Achse auch exzentrisch angeordnet sein, d.h daß sich die Achse vom Vorratsbehälter 10 und Mischpumpe 2 unterhalb des Bodens des Behälters nicht schneiden. Dies ist dann notwendig, wenn der Rührmotor 16 nach aussen verlegt, d.h. unter den Boden des Vorratsbehälters 10 gehängt wird.In a further, conceivable embodiment of the machine can the mixing pump 2 can also be arranged eccentrically with its axis, i.e. that it is the axis of the storage container 10 and mixing pump 2 below the bottom of the container do not cut. This is necessary when the stirrer motor 16 is moved outside, i.e., hung under the bottom of the reservoir 10.

Im ganzen ergibt sich bei dieser neuen Anordnung der Vorzug, daß geringe Einfüllhöhe, gzßes Füllvolumen und sichere Austragung des Schüttgutes bis zum Entleermoment sichergestellt ist, was für die Praxis große Bedeutung hat.All in all, this new arrangement has the advantage that low Filling height, large filling volume and safe discharge of the bulk material up to the moment of emptying is ensured, which is of great importance in practice.
